Liquid dangerous chemical injection device

Abstract

The invention relates to the technical field of chemical injection equipment, in particular to a liquid dangerous chemical injection device. A bottom frame, a supporting table and supporting frames are included. The supporting table is welded to the top end of the bottom frame. The supporting frames are welded to the left side and the right side of the top end of the supporting table. A tank is welded to the top end of the supporting frame. An inner cavity of the tank is connected with an inner tank through screws. The bottom end of the right side of the tank is fixedly provided with a monitoring mechanism. A discharging pipe is connected to the bottom end of the inner tank through a flange. The outer wall of the discharging pipe is in screw joint with a first valve. A conveying mechanismis connected to the bottom end of a water pump through screws. After injection, the conveying mechanism is closed, the conveying space of the water pump can be closed, accordingly, the phenomenon of backflow can be avoided, and the phenomenon that after dangerous chemicals corrode the water pump, the corrosion situation is not found in time, and consequently leakage is caused is avoided, the leakage volume can be rapidly observed during leakage, the situations of pollution or explosion or the like due to leakage and evaporation of the liquid dangerous chemicals are prevented, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of chemical injection equipment, in particular to a liquid dangerous chemical injection device. Background technique [0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that are poisonous, corrosive, explosive, burning, and combustion-supporting, and are harmful to the human body, facilities, and the environment. At present, in the production process of the chemical industry, they are often used Some chemical devices that need to be injected with liquid dangerous chemicals, such as: ethylene cracking device, etc., during the operation of the ethylene cracking device, due to the different selection of raw materials, it is often necessary to inject other liquid dangerous chemicals into the cracking furnace other than the reaction raw materials. To reduce the concentration of carbon monoxide (CO) and carbon dioxide (CO2) produced in the radiant tube of the cracking furnace, so as to...

AI Technical Summary

Problems solved by technology

[0003] The injection device is a complete set of devices that inject chemical liquids into various systems according to the process flow. Through different process designs, various solid and liquid chemical solutions are precisely configured and then added. However, in the existing liquid dangerous chemicals In the injection device, since the liquid chemical will corrode the water pump and the tank, it is very easy to leak, and it is easy to cause the liquid dangerous chemical to evaporate and cause pollution or explosion, which has great safety hazards and is not conducive to widespread promotion
